An ultrasonic treatment apparatus according to the present invention includes: a treatment tank capable of containing a treatment object and a treatment liquid for immersing the treatment object; and an ultrasonic application mechanism that applies ultrasonic waves to the treatment liquid, wherein the treatment tank has a long axis where cross-sectional shapes are substantially identical to each other, and a wall surface to a scheduled liquid level height line of the treatment liquid is formed by a concave surface, and the ultrasonic application mechanism is installed at a position where an angle &#x3b8; formed by a normal line of an oscillation surface of ultrasonic waves and the scheduled liquid level line of the treatment liquid is 5&#xb0; to 80&#xb0;.

Ultrasonic treatment apparatus

An ultrasonic cleaning equipment () according to the present invention includes a treatment tank () that stores a cleaning liquid that cleans an object to be cleaned and in which the object to be cleaned is immersed; an ultrasonic application mechanism () that applies ultrasonic waves to the cleaning liquid retained in an interior of the treatment tank; and a curved surface member () that is located in a range defined by an angle of inclination from a perpendicular direction in an end portion of a vibrating surface of the ultrasonic application mechanism to an outside with respect to the vibrating surface and that is held on a wall surface and/or a bottom surface of the treatment tank.
